I for one would be incensed by a minister who made the announcements you describe.
Please keep in mind that it was numerous men in the congregation who asked the pastor to make the request of the ladies; this was not the rule of a heavy-handed pastor. As a woman, I felt no offense to the request and indeed, felt badly for the guys who were driven on the expedient of needing to ask. I imagine they felt a lot of relief just hearing his request and that it validated their need to be as free of distraction in the house of the Lord as possible (there are few places where that freedom can be found these days). I never heard any women complain about it, but I can see how someone who came in new to the church might wonder, especially those whose manner of dressing had prompted the request.
If I have a nice car and a neighbor lusts after it, am I going to sell the car? No. But this area of how we present our own selves has a difference to it. We can't hardly throw away our bodies if someone finds them attractive. ;-) The fine line is discerned in having a clear conscience that is governed by His Word and His Spirit that we are doing what we can to please Him and treat our "brothers" with honor. That includes, as in the case of my church, the congregation being responsive to instruction or correction when it is needing to be given.
Reading this thread has been a real eye-opener for me, as I thought many more women were aware of the effects of the female body on a man when he sees it revealed. I know as a young woman, before I got married, I did not realize the extent of how visually, immediately ignited men are by sight. But God made them that way because His heart is in perpetuating the race and He designed the two sexes to find fulfillment in each other; if women weren't fantastically, irresistibly attractive to men, the men would be out working and skiing, anything but settling down.
I found it interesting that none of the guys on this thread have objected to what I've been writing as untrue, and some have agreed with me in specifics. This whole issue has been swept under the carpet for so long that our society groans when the issue is examined. A lack of appropriate, profound sexual and emotional intimacy in marriages, an inability to relate to each other in meaningful ways, etc., ad nauseum, feeds and perpetuates the cycles, the divorces, the men (including husbands) who are addicted to porn, etc. God's heart is to turn the tide.
Bless you.
